Does boiling water remove microplastics? What works outside the lab
In a 2024 lab study, limescale trapped test plastic particles as hard water boiled. Here is what that does and doesn't mean for your kettle.

Do glass bottles have more microplastics than plastic ones?
A 2025 French study found more particles in some glass-bottled drinks. Most of them matched the paint on the bottles' metal caps.
